Kate Martin Is Making The Most Of Her WNBA Opportunity

Martin starred alongside Caitlin Clark at Iowa but wasn’t sure she would get drafted; she was only holding out hope.

She’s played very well over the first few weeks of the WNBA season, with the Aces surprisingly picking her in the second round.

“She executed our schemes really well. She plays so hard. Her sense of urgency has really been there the whole time,” head coach Becky Hammond told reporters recently.

The Aces are scheduled to play Angel Reese and the Chicago Sky this Thursday following a loss to the Connecticut Sun last Friday.
